| The :command:`set(CACHE)` does not remove a normal variable of the same name. |
| |
| Starting with CMake 3.21, the :command:`set(CACHE)` does not remove, in the |
| current scope, any normal variable with the same name. |
| |
| The ``OLD`` behavior for this policy is to have the :command:`set(CACHE)` |
| command removing the normal variable of the same name, if any. The ``NEW`` |
| behavior for this policy is to keep the normal variable of the same name. |
| |
| This policy was introduced in CMake version 3.21. Use the |
| :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly. |
| Unlike many policies, CMake version |release| does *not* warn when the policy |
| is not set and simply uses ``OLD`` behavior. See documentation of the |
| :variable:`CMAKE_POLICY_WARNING_CMP0126 <CMAKE_POLICY_WARNING_CMP<NNNN>>` |
| variable to control the warning. |
